This study evaluated the effect of functional characteristics of the fabric for Bikram yoga clothing and fit measured in clothing pressure on the wearer's physiological response and perceptive sensation before and after exercise in hot conditions and during a resting period in standard conditions. The test garment consisted of two tops (T1, T2) and two pants (P1, P2) each with different functional characteristics of fabric. Using various combinations of the test garments, assessment of the thermal sensation and comfort was performed before/after yoga and after resting. This study revealed that thermal sensation and wearing comfort significantly changed based on the functionality of the fabric of top garment before the exercise period. In addition, the results showed that based on clothing pressure, the feeling of comfort was different between before yoga and after resting. The appropriate choice of fabric material was important when constructing Bikram yoga clothing worn in hot conditions; however, level of clothing pressure was also found to be an essential design factor for comfort during rest after exercise.

This exploratory research was intended to develop and test a slacks pattern based upon conic model. Data came from measurements of photograph of three subjects. Silhouette of slacks was close fit on waist and hip and loose under hip level. This three-dimensional form was modeled with truncated cones. This conic model was truncated by plane of the waist level, the abdomen level, the hip level, the crotch level and the ankle level parallel to the floor. Two models that have differences in back part of the model were tested. Drafted patterns from two models were taken for each subject. Drafted experimental pattern was operated for slacks pattern. The first step was to make sideseam. Parts over crotch level were moved to both sides. And then to make waistdarts. Experimental pattern had two darts each in front and back. Each experimental slacks was evaluated by sensory test to appearance and comfort by five judges. The results can be summarized as follows. 1) Appearance and comfort of experimental pattern were judged to be satisfactory. Especially these patterns were fitted we18 in waist darts front and back. So we evaluated that was proper pattern for slacks. 2) Model 2 was better in appearance than model 1. But Model 1 was more comfortable in non significant difference. This was supposed to be resulted from fit more closely of model 2. 3) considering preceding results, this geometric model based upon truncated cone was applicable for slacks pattern.

After the Korea-Japan comfort women's agreement, two films and were released with the audience's attention. Both films deal with the friendship of 'comfort women' girls. Unlike the existing 'comfort women' narratives, these two films are building a women's space based on a kind of sisterhood. The emergence of a new generation extends the story of personal friendship to the community level of sisterhood. In particular, suggests the possibility of a testimony that the 'comfort women' grandmother passes testimony to a new generation of women. In the cinematic present, it shows the possibility of feminist thinking of the 'comfort women' narrative. However, the representation of the colonial period does not deviate much from the existing patriarchal nationalistic viewpoint. It is typical that the 'comfort women' characters are still set with a pure and innocent girls of Chosun era.

The purpose of this study is to provide the thermal comfort range according to the residential style and clothing level at radiant floor heating space, and compare the annual energy consumption and energy cost for each condition. Lower neutral point temperature has been stood for floor sitting style than chair sitting style, which appears that the thermal sensation was affected by local heat transfer between floor surface and the human body. The result of research indicates that neutral point temperature was in inverse proportion with the clothing level. It is interpreted that the increasing of clothing level results decrement of heat loss from human body, and is available to achieve same thermal comfort at lower room temperature. It was analyzed that the floor sitting style is more economical residential style than the chair sitting style, because the energy consumption of the floor sitting style is saved by 6.0% in average to compare with that of the chair sitting style. It is analyzed that energy consumption has been decreased by 13.5% with the clothing level of 1.2 Clo than with that of 1.0 Clo, and decreased by 18.0% than with that of 0.8 Clo, which explains that the energy saving can be achieved with the variation in life habit to increase the clothing level.

The purpose of this study is to help male-clothing companies in investigating male shopping orientation and information source with clothing benefits. As for the method of the research, 428 male consumers were the object for the data of this research. The major results of this study are as follows : 1. The dimensions of clothing benefits were composed of the better appearances, the social status, the personality and the comfort. The dimensions of shopping orientation were composed of pleasant, planned, loyal and individual shopping orientations. 2. The consumer with clothing benefits were classified three groups: better appearances, comfort and careless. In the consumer's classified shopping orientation the group of pursuing personality and better appearances were given higher score at each level, while careless group was given the lowest score at each level of shopping orientation. 3. In case of using information source with classified consumers, the group of personality and better appearances got information through the marketer-oriented information source and neutral information source, the group of pursuing comfort got lots of information through human information source, the group seldom used all information source.

In this study, the excessive noise and vibration phenomena of a high-speed Ro/Ro passenger ship were analyzed, and a countermeasure was taken based on them. This ship was granted a comfort class notation by the classification society, which was COMFORT-VIBRATION-II and COMFORT-NOISE-CREW-II. However, unfortunately, excessive noise and vibration in the aft part of the ship were delivered from the twin shaft propellers, and therefore the Class Requirement was not satisfied before delivery. In order to obtain the class notation, all of the concerned parties came to an agreement to reduce the noise and vibration level during operation after delivery because a seasonal ferry service was already scheduled and the cabin was fully booked. The root cause of the massive amount of noise and vibration was mainly the propeller-induced excitation pulse and beating that occurred from the mismatch of the rotating speeds of the two shaft lines. A 1st order vibrating force and beating phenomena existed in the propeller. Thus, a reduction of the excitation force, elimination of the beating phenomena, and decrease of the noise level at the aft area cabins and public spaces were required. In addition, structural reinforcements were conducted using pillars and additional girders at the aft part of the decks.

The purposes of this study are to analyze shopmasters' knowledge of apparel merchandise and textile recognition and to investigate the effects of demographic variables on them. Shopmasters' knowledge of apparel merchandise was analyzed on a factor basis. Four factors of apparel merchandise were fashion property, material property, function property and management property. The textile knowledge level of shopmasters was 72.44%. Considering each part of textile knowledge, basic property was 74.69%, comfort 72.17%, management 68.36% and finishing 77.33%. The level of recognition in finishing area was the highest and the level of recognition in management area was the lowest. There were significant differences in the textile knowledge by gender and working period. Female's textile knowledge level was higher. The longer the working period is, the higher the level of textile knowledge is. Shopmasters recognized the finishing area better than university students did. But both of the groups didn't recognize the management area well.

This study aimed to identify the effects of sports participation motives, the involvement in choosing sportswear, and the satisfaction with/perceived importance of sportswear functionality, on customers' repurchase intentions. A total of 185 survey questionnaires were analyzed after surveying 200 female undergraduates in their 20s. The research results are as follows. First, the participation motives for sports were categorized as follows. A factor analysis conducted on 13 questions yielded 4 factors. Factor 1 included consideration about socializing and pleasure, factor 2 privileged ostentation, factor 3 was concerned with enhancing health, and factor 4 was about maintaining appearance. Second, the various effects of different sports participation motives, of the satisfaction with functionality, and of the involvement in buying sportswear on customers' repurchase intentions were analyzed. The intention to repurchase sportswear was considered as a dependent variable, while the motives for participating in sports, the satisfaction with functionality, and the level of involvement were treated as independent variables. A multiple regression analysis using these variables showed that the satisfaction with functionality and involvement in choosing sportswear had a significant impact on the intention to repurchase sportswear. Third, looking at how different participation motives for sports affected the importance of sportswear functionality, the motives related to socializing and pleasure and ostentation, the sub-factors in sports participation motives, significantly increased the importance of comfort. Motives related to enhancing health and maintaining appearance, on the other hand, were found to affect the importance of sports performance. Fourth, a MANOVA was performed to examine the difference in the importance of functionality between those consumers highly involved in sportswear-buying and those less involved. Those with a high level of involvement were found to prioritize sports performance over comfort. Those with a low level of involvement were shown to place a greater emphasis on comfort.

The assessment of wind-induced motion plays an important role in the development and design of the majority of today's structures that push the limits of engineering knowledge. A vital part of the design is the prediction of wind-induced tall building motion and the assessment of its effects on occupant comfort. Little of the research that has led to the development of the various international standards for occupant comfort criteria have considered the effects of the low-frequency motion on task performance and interference with building occupants' daily activities. It has only recently become more widely recognized that it is no longer reasonable to assume that the level of motion that a tall building undergoes in a windstorm will fall below an occupants' level of perception and little is known about how this motion perception could also impact on task performance. Experimental research was conducted to evaluate the performance of individuals engaged in a manual tracking task while subjected to low level vibration in the frequency range of 0.125 Hz-0.50 Hz. The investigations were carried out under narrow-band random vibration with accelerations ranging from 2 milli-g to 30 milli-g (where 1 milli-g = 0.0098 $m/s^2$) and included a control condition. The frequencies and accelerations simulated are representative of the level of motion expected to occur in a tall building (heights in the range of 100 m -350 m) once every few months to once every few years. Performance of the test subjects with and without vibration was determined for 15 separate test conditions and evaluated in terms of time taken to complete a task and accuracy per trial. Overall, the performance under the vibration conditions did not vary significantly from that of the control condition, nor was there a statistically significant degradation or improvement trend in performance ability as a function of increasing frequency or acceleration.
